Cleveland Cobalt End Mill 3/4" 4FL TiCN

This cobalt square end mill carries a TiCN coating and a 30-degree helix on a 3/4-inch shank. Four flutes and a 1-5/8-inch length of cut give it the rigidity to finish steel and stainless workpieces in a single pass. The tool is new and ready for CNC or manual milling setups. Right-hand cutting direction matches standard machine rotation.

TiCN coating extends tool life in finishing passes

The titanium carbonitride layer reduces built-up edge and resists heat better than uncoated cobalt, so the cutter holds size longer on abrasive alloys. A 0.000-inch corner radius leaves a true square profile without blending marks. Single-end geometry keeps the price down for shops that resharpen rather than rotate stock.

3/4-inch diameter suits medium finishing cuts

At 3-7/8 inches overall, the tool clears typical vise jaws while reaching into pockets. Four flutes limit chip space, so deep slotting or heavy roughing will load the gullets and demand reduced feed rates. Builders who need longer reach, more flutes or a ball-nose profile should select a different cutter.

Questions about this item

How often does the TiCN coating on this 3/4 inch cobalt end mill need to be replaced?

The TiCN finish on this 3/4 inch cobalt end mill is a surface coating that wears away during use; the tool itself is replaced once the cutting edges dull or the coating is consumed.

What limits continuous cutting with this 4-flute 30-degree helix end mill?

Heat buildup at the cutting edges limits sustained use; the 30-degree helix and four flutes manage chip evacuation, but prolonged heavy cuts will raise temperatures until the cobalt substrate softens.

How much noise and heat does this 3-7/8 inch overall length end mill generate during all-day finishing passes?

Noise and heat depend on the machine spindle, workpiece material and cutting parameters; the tool itself produces no sound or heat until it engages the cut, where the 30-degree helix and TiCN finish help reduce friction.
